BREEAM Hea 01: visual comfort

What Hea 01 assesses and the evidence needed
| Requirement | Typical evidence |
|---|---|
| Glare control | Blind or shading specification |
| Daylighting | Daylight modelling report |
| View out | Plans showing window distances |
| Internal and external lighting levels and zoning | Lighting design and controls specification |
Exact criteria and credit numbers depend on the scheme and manual version your project is registered under. Your assessor confirms them at pre-assessment.
How to secure Hea 01 without extra cost
- Agree the target at pre-assessment, before RIBA Stage 2.
- Give the responsible designer or contractor a clear evidence list.
- Check the evidence at design stage so nothing is lost at post-construction review.
